Well guys i just blew my motor up at 6000 miles. All my mods are on my sig. To be honest i think the played a big role in burning a hole through my piston and the rings ate the #1cylinder wall apart, but it was all worth it while it lasted. so im buliding from the ground up. I need some preferences on best pistons and rods. port the head or not port it.Thanks guys. ill get some pics up after i get out of this field excerise that im in.

The tune killed it.

Weisco seems to be the popular choice for pistons. Are you goona sleeve the block or get another stock block? If you're staying stock block, I would suggest a different setup as opposed to a sleeved block.

fosterSS

yea im pretty sure the tune did too, when i had it tuned i wanted the most aggressive tune vince could get me so it was my choice. the block is going to darton to get 4 new sleeves.

I want to know why the pistons aren't surviving....

Is it because of the amount of heat caused by the little k04 overspinning?
Or boost levels?

Will this be solved long term with a bigger turbo with more flow causing less heat?

beast10007

sucks dude but sounds like you where ready for it

any ways what size turbo are you going to use? Stock?

fosterSS

To be honest idk, I got a few ideas like the s256 or precisions sc62. It just depends how the motor build goes. If I get lazy I'm gonna just get zzp's kit and get it tuned.

its gotta be the heat issues. When I was runnin 28 lbs it wouldn't hold long . we are pushing the limits of this small turbo and finding out what the consequences are of doing so.

Another infiboost tune bites the dust.

28 psi is too much on the little k04

did you data log your tune so vince could fine tune it?

Ya im pretty sure i fried my piston rings in my car. 11k on it, ran 29psi for bout 2-3k. It sucks but at least the dealer is covering it!

fosterSS

Yes the dealer that downloaded the tune on my pcm, prior to installing the tune we did 6 data logs. Under a load in like 5th gear at like 40 it would max out my boost gauge at 30 lbs

Stamina

That alone is not good for it.

Too far past 24psi or so, the rings are expanding to the point where the gap goes away and the ring's ends start pressing against each other until failure. The solution is to keep boost lower or gap the rings wider.

Wisecos have a much wider ring gap. This, in addition to them being forged, will allow for more boost, nitrous, and/or larger turbos.

Were you doing 5th gear pulls before it died? That seems to be the common thing with really high boost tunes failing!

blackrocky

show us some pics?????

glhs379

5th gear pulls on high boost=no good!

if you ain't won by the time you hit 5th, the race is over! lol

raver0789

Ok question....

Seeing how these pistons are frying with this infiboost tune...
Would the setup be somewhat reliable if you put in Wiseco LNF forged pistons and ran that tune?
I would think the pistons wouldn't go.
The turbo would eventually...

The forged pistons would also break, just not as quickly. Maybe a few extra seconds

Yea it would probably be fine, but the turbo would say f you after awhile

ecotecturbo

I would get a better turbo if your building the motor.

ItalianJoe1

Forged pistons are a ton stronger and would probably withstand the abuse, but the problem is trying to overspin the stock turbo and pushing it out of it's happy range. Leave it be at 23psi or get a bigger turbo.

Idiot lol

fosterSS

no i wasnt doing 5th gear pulls. when the motor did give out i was at my stock tune .

i would be stupid to use the stock turbo after the motor is built. im deffinally going bigger. i wont be out of the field untill the 31 of july guys so sorry it will be a few weeks before i can get my pics up.

What I find disturbing is that this assclown is tuning so many people and runs 28psi on a stock lnf k04 car.
Now Im not anything close to a full blown tuner but I know what you can and cant do and if a customer would ask for that I would explain to them why I am not able to do that, not blow their ******* motor.
Such a joke.

fosterSS

I started out with the BSR/PPC from hahn and io wanted more. I did want a really aggressive tune i knew it would beat the motor up but, if i knew it would have been at 6000 miles on a car that i have owned since january of 09 i wouldnt have went that route. Thats one thing i will say there was no warning from the tuner or trifecta that it is possible just possible that your motor might self destruct. but on the same note us the customer want the baddest cars on the street. Its hard to say its really anyones fault at this point.

Yeah, but it's the tuners responsibility to say either say no or warn you you're getting to motor popping territory. Which he obv fails at doing. Like I said I wouldn't even give someone something like that just stupid.
